' 3Claims. (01. 129-20) This invention appertains to card indexes and the like, and more particularly to a novel sheet for loose leaf binders having stepped pockets for the reception of index cards, or other matter to be filed.

I am aware that it has been proposed to provide sheets for loose leaf binders having pockets capable of being used for detachably holding index cards. However, all of these devices with which I am familiar are open to serious objections. These sheets are usually of a bulky character, some are expensive to manufacture, and others fail to stand up under use.

Some of the sheets are open to all of the objections outlined.

It is therefore one of the salient objects of my invention to provide a sheet for loose leaf binders having a series of pockets on the opposite faces thereof, which will be simple and inexpensive to manufacture, one which will possess a minimum thickness, and one which will stand up under constant use.

Another important object of my invention is the provision of a sheet for the reception of index cards and the like, embodying a plurality of transversely disposed pockets of a V-shape in cross section, placed partially one within the other, with binding strips on the longitudinal edges of the pockets to hold the same in an assembled condition.

A further important object of my invention is the provision of a leaf for loose leaf binders having pockets on the opposite faces thereof formed from a plurality of sheets folded back upon themselves, the folded sheets being placed partially one within the other to form a series of stepped pockets on opposite sides of the leaf, and held in such position by reinforcing binding strips folded around the longitudinal edges of the leaf.

With these and other objects in View, the in vention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawing, in which drawingz- Figure 1 is a front elevation of my improved card index leaf showing parts thereof broken away and in section to illustrate structural details.

Figure 2 is a fragmentary longitudinal section through the leaf taken on the line 2-2 of Figure 1.

Figure 3 is a fragmentary transverse section through the leaf taken on the line 33 of Figure 1, looking in the direction of the arrows.

Referring to the drawing in detail, wherein similar reference characters designate corresponding parts through the several views, the letter A generally indicates my improved card index leaf. This leaf A embodies a plurality of folded sheets 5 partially placed one within the other, as is clearly shown in Figure 2 of the drawing. Each of the sheets 5 is folded back upon itself on a central longitudinal line, so as to form a substantially V-shaped structure in cross section. Thus each folded sheet 5 includes like side walls or wings 6, and a connecting bottom wall I. In placing the folded sheets one within the other, it is to be noted that the bottom walls of the folded sheets are spaced so that the outer 1ongitudinal edges of the side walls or wings of one sheet will project beyond the side walls or wings of the adjacent sheet. sheet 5 I preferably place a single, unfolded, dividing sheet 8, for a purpose which will be later set forth.

All of the sheets 5 and the sheet 8 are held in their assembled form, preferably by binding strips 9 and III, which are folded around the longitudinal edges of the leaf A. The binding strips 9 and Hi can be formed of paper or cloth, and their inner faces are provided with a suitable adhesive so as to firmly adhere to the various folded sheets 5 and the dividing sheet 8. The folded sheets 5 and the dividing sheet 8 are also preferably formed from paper .of the desired thickness, but obviously fabric can be employed.

By constructing a leaf in the manner described above, I provide a series of pockets l l and E2 on opposite sides of the leaf, with the pockets disposed in stepped relation on opposite sides of the leaf.

Obviously, the dividing sheet or strip 8 forms the uppermost folded sheet 5 of the leaf into a pair of pockets, and finishes the upper end of the leaf. The strip or sheet 8 is the same size as the sheets 5 before the folding thereof. Thus the necessity of providing different sized sheets in the making of the leaf is eliminated.

While I have stated that the sheets 5 and 8 are connected by binding strips 9 and I ll, these sheets can be connected by a line of stitching adjacent to their side edges, where every economy is desired. If preferred, stitching 9' can be utilized for connecting the sheets together in their assembled condition, after which the binding or finishing strips 9 andjfl can be utilized to hide the stitching from view.

In the uppermost folded One longitudinal edge of the leaf can be provided with any number of desired openings l3 for the reception of rings or like elements of a loose leaf binder. The leaves may be used without a binder, and can be filed within a drawer, box, or other suitable container, or otherwise used independently.

From the foregoing it can be seen that I have provided an exceptionally simple and durable form of leaf for receiving index cards and the like, which can be manufactured at an exceeding- 1y low cost.

Changes in details may be made without departing from the spirit or scope of this invention, but what I claim as new is: v

1. A card index comprising a series of paper or 2. A card index comprising a plurality of flexible sheets each folded upon a longitudinal line defining side walls, the folded sheets being placed partially one within the other with the side walls in engaged relation and the folded portions in spaced relation, a dividing sheet disposed in the uppermost folded sheet between the side walls thereof, and stitching connecting the ends of all of the sheets together, whereby series of stepped pockets are formed on the opposite sides thereof.

3. A card index comprising a series of flexible sheets each folded upon a longitudinal line back upon itself defining like side walls, the folded sheets being placed one within the other with the side walls in engaged relation and the folded portions in spaced relation, a dividing sheet disposed in the uppermost folded sheet between the side walls thereof and with its inner edge engaging the folded portion of said sheet, and binding strips folded over and secured to the ends of these 20 sheets.
